Description
Известные турбулизаторы воздушного потока в зоне пограничного сло обладают тем недостатком, что они не обеснечпвают устранени срьшного флаттера или вибрации лонастей ротора вертолета нли винта.The known air flow turbulizers in the boundary layer zone have the disadvantage that they do not provide for the elimination of the slug flutter or vibration of the rotor's rotor hollows or the screw.
Предлагаемый турбулизатор, лишен этих недостатков. Супиюсть изобретени заключаетс в том, что турбулизатор выполнен в виде гибкой полосы из упругой ткани, например, найлона, соединенной с лонастью заподлицо с верхней поверхностью профил .The proposed turbulizer is devoid of these disadvantages. The advantage of the invention is that the turbulator is made in the form of a flexible strip of elastic fabric, such as nylon, which is connected to the laster flush with the upper surface of the profile.
На чертеже схематично изображена лопасть (крыло) с расположенным на ней описываемым турбулизатором.The drawing shows schematically a blade (wing) with the described turbulator located on it.
На верхней поверхности лопасти (или крыла) / прикреплен своей передней кромкой турбулизатор 2, представл ющий собой полоску из эластичного материала.A turbulizer 2, which is a strip of elastic material, is attached to the upper surface of the blade (or wing) / with its front edge.
При возникновении срыва потока эта полоска начинает колебатьс , турбулизирз поток, чем зат гивает по в;1енне опасных срывиых колебаний конструкции.When a flow stall occurs, this strip begins to oscillate, turbulize the flow, and this causes the structure to contain dangerous vibrations of the structure.
Предмет изобретени Subject invention
Турбулизатор воздушного потока в зоне пограничного сло , например , дл лопасти ротора вертолета или воздун1ного винта, работающей в услови х интенсивного срыва потока, отличающийс тем, что, с целью устранени срыва флаттера, а также уменьшени вибраций лопастей ротора вертолета или воздущного винта, он выполнен в виде гибкой полосы из прочной ткани, например, найлона, соединенной с .топастыо заподлицо с поверхностью профил .An air flow turbulizer in the boundary layer zone, for example, for a rotor blade of a helicopter or a propeller operating under conditions of intense flow disruption, characterized in that it is made in the form of a flexible strip of durable fabric, for example, nylon, connected to the .pasto flush with the surface of the profile.
